wow I am really taken back by this the "TEXTURE" alone is very detailed and deep, I love the look on his face a great emotion for the character, so it looks like there is a dark frame I would suggest adding some lighting effect on it and also adding something in the backround to show what he might be scared of, anyways nice art work.
